Turning Stainless Steel Bolt into Useful Pneumatic Tool - Air Graver without Lathe Version - 2

In this video, I turned the stainless steel bolt into a pneumatic air graver. This tool is often used in jewelry work for doing engraving stuff. This is an absolute hell of a build. In past, I made the first version of air graver but for that, you need to modify the car air compressor to use the graver. I would say, that type of graver is far easier than this one because there weren't too much-complicated parts in that one but this version consists of so many different small parts. Making this tool without a lathe is definitely a challenging task and if you go a tiny bit off then the tool is not going to work at all due to this, I failed two times in making the piston absolutely right. To me it took near about 13days to complete it and during this, I need to rebuild the main barrel because the hole I drilled was 10mm and after polishing and honing the size gets increased and the piston was too loose. I almost ended up giving this build but a little boost helped to give it one more try and it worked as expected. if you wanted to build a much easier version of this graver then definitely recommend you to watch my previous video linked down below and if you love my work then definitely hit the like button. The material used in this is a 304-grade stainless steel bolt. Stainless is a work-hardened material and during the drilling operation, it gets hardened. During this build, I need to soften the material because it was making loud noise and the bit gets dull quite fast. For the main barrel the hole I drilled is 9.7 mm and after polishing it gets to 9.87mm. The length of the barrel is kept around 47mm and on both ends, I need to grind up to 12.7mm for 1/2" UNF thread. For the piston, I use a 10mm high-speed steel rod and I need to grind it a little bit to ease the material removal process. For the air inlet, I made my custom elbow fitting, and the threads used in that are 5mm tap with .5mm thread pitch. The pommel is made out of a bolt head and then welded together to make that mushroom kind of shape. The build required a high amount of accuracy and it would be good to do with lathe if you don't want to waste your time.
